Question

At low pressure if RT =, (a is vander Waal's constant) then the volume occupied by a real gas is-

• A. $\frac { 2 \mathrm { RT } } { \mathrm { P } }$
• B.
• C. $\frac { \mathrm { RT } } { 2 \mathrm { P } }$
• D. $\frac { 2 \mathrm { RT } } { \sqrt { \mathrm { P } } }$

Answer 1

Answer: (C)

$\frac { \mathrm { RT } } { 2 \mathrm { P } }$

Answer 2

A low pressure,

$\left( P + \frac { a } { v ^ { 2 } } \right)$ (v) = RT

\ Pv² – RTv + a = 0

\ v = =
